Power Line Measurement Method Based on Vertical Baseline Stereo Camera

Conducting regular inspections and measurements of power lines is an important way to ensure the stability and security of transmission line. For the problem of being poor reliability, poor flexibility and high cost, a power line measurement method based on vertical baseline photography is proposed and studied: Line patrol officers use portable vertical baseline stereo camera shooting in the outdoor field, and measure accurately in the stereo image taken in or after patrol. This paper describes the system design and technical methods, and analyzes the key technologies in the system calibration and measurement, and uses several sets of experiments to prove the accuracy and feasibility of this method.
